unix - How to attach a file using mail command on Linux?

I'm on a server running a Linux shell.
I need to mail a simple file to a recipient.
How to do this, prefereably using only the mail command?

UPDATE: got a good solution, using mutt instead:

$ echo | mutt -a syslogs.tar.gz admin@domain.org

Answer

Example using uuencode:

uuencode surfing.jpeg surfing.jpeg | mail sylvia@home.com

Note:

you may apt install sharutils to have uuencode command
